- As seen at WWE's Payback pay-per-view, WWE had United States Champion Dean Ambrose mock The Undertaker and attempt his Old School move. There were also mentions by the announcers on the pay-per-view and last night's RAW. This is all being done for a potential Kane and The Undertaker vs. The Shield feud for SummerSlam. There's actually a belief within WWE, among some people, that Taker will decide to work the match.
